On Virtual and Mixed Reality Intelligent Environments

This special issue addresses core topics on Virtual and Mixed Reality Intelligent Environments. The conventional definitions for virtual and mixed reality systems, e.g., in [1-3], do not require that such environments should be intelligent or even reactive. However, most useful applications of virtual reality can be considered intelligent in the sense that the environment changes and reacts to the actions of the user. This journal has traditionally focused on ambient intelligence and smart environments which are considered to be real physical environments with sensors and actuators rather than artificial intelligent environments based on software only. The goal of this thematic issue is to bring these two concepts together.
